To all whom it may concern Be it known that T, EDWARD RICHTER, a subject of the King of Prussia, residing at Plauen, in the Voigtland, Germany, have invented certain new and useful Improvements in Processes of Preparing an Oil, of which the following is a full, clear, and exact specification.

Tf salicylate of sodium, hydrochlorate of quinin, ethyl-ester of the carbamic acid and sodium diiodo-p-phenol sulfonate are mixed in equal parts, after the salts have been well triturated, the triturated substances then dissolved in a small quantity of water, the moist mixture thus obtained heated in a test tube and first a 10% sulfuric acid, and subsequently a 50% sulfuric acid is added, it will be observed, that a thick oily body settles at the bottom of the heated tube, which oily body will still remain oily at about 20 centigrade.

Example: 1.5 gram of salicylate of sodium and 0.5 gr. each of ethyl-ester of the carbamic acid and of hydrochlorate of quinin, respectively, are mixed and titurated with each other, the mixture is then placed into a test tube, 2 com. of distilled water is added, and thereupon. first, 0.8 com. of a ten per cent. sulfuric acid and then 0.3 ccm. of a fifty per cent. sulfuric acid is added and the whole is carefully heated, a light yellow oil will then settle at the bot tom of the tube. The yield of this oily body will be about coin. The addition of the sodium d.iiodop-ph.enol sulfonate is not imperative. The form, of the oily body obtained and its quantity are always constant. he heavy oily body thus obtained has the characteristic property of absorbing}; certain metal oxids and protoxids from sulfate solutions, and also anilin dyes and other dyes. [is hereinbefore said certain metal oxide and protoxids will be absorbed by the oil. If, for instance the solution of a metal OXlCl or protcxid such as solution of hydrated ferrous arbonate (mineral water) is substituted for the water in the above example, the protoxid will be drawn down into the oil forming, and in consequence of the ferrous compound the oil will assume a reddish brown color. The same will be the case if ferrous onid is added in a solid form to the above example. A dye which suffers the Specification of Letters Fatent.

same absorption is eosin. If any of such substances which will be absorbed, are contained in the sulfuric acid added in a diluted condition, they will be greedily ab- SOl'bQd by the oily body formed in the above described process, so that the oil is practically dyed in stat u nascemii. The oil behaves in this respect similar to lac.

Another characteristic feature of the oil product is the following: if the separated warm oil is poured into a porcelain dish, it may be triturated with elements such as sulfur, carbon, mercury, so that the oil will gradually assume a resinous viscid consistence. -lnstead of with elements it can also be triturated with other chemical dyes, such as minium, zinc oxid, oxid of manganese and the like or also with anilin dyes. The oil thus acts in both cases as color lac. But it may also be used for preparing with its aid fat-free salr'es by discontinuing the trituration before perfect dryness is obtained, or continuing, the treatment with American vaselinc. The triturations with elements such as sulfur, carbon. or mercury may also be used by submitting them to a further treatment with chemicals. l ly the hercinbefore described. methods it is possible to prepare chemical medicines and medicinal prqiaratious which may be used against affections of the skin, cancer or l'ues.

The oily body when mixed with quicksilver meta. forms an excellent remedy for syphilis and when mixed with arsenic and other chemicals a remedy for infectious dis eases of a general nature.

I claim:

The process of preparing an oily body by mixinr; salicylato of sodium, a hydrochlorate of quinin, ethyl-ester of the carbamic acid, adding; a small quantity of water and thereupon adding a small quantity of a ten per cent. sulfuric acid, and finally again a small quantity of the sulfuric acid at a con centration of fifty per cent. and carefully heating the whole.

in testimony whereof I ailix my signature in presence of two witnesses.
